Specialty PTFE Fillers & Compounds
Sag Engineers formulates filled PTFE composites to boost compressive strength, enhance thermal conductivity, reduce thermal expansion, and minimize cold flow.
Virgin PTFE
100% pure fluoropolymer. Highest chemical resistance, outstanding electrical dielectric properties, FDA compliant for food & pharmaceuticals.
Bronze Filled (40-60%)
Highest thermal conductivity and load-bearing capacity. Ideal for hydraulic piston rings, guide rings, and heavy mechanical wear pads.
Glass Filled (15-25%)
Significantly decreases creep and cold flow under static compression. Excellent for valve seats, gaskets, and chemical pump bearings.
Carbon / Graphite Filled
High wear resistance under dry friction conditions. Excellent for non-lubricated gas compressors, rider rings, and water application seals.
Key Performance Characteristics
Learn why PTFE is the benchmark fluoropolymer for extreme industrial conditions across the globe.
Chemical Resistance
Inert to virtually all aggressive acids, alkalis, and solvents up to 260°C continuous service. Not affected by aqua regia or organic solvents.
Electrical & Dielectric Strength
Superior electrical insulation, zero tracking, highest surface resistivity, and ultra-low dielectric dissipation across all frequencies.
Thermal & Cryogenic Stability
Continuous service from cryogenic temperatures (-206°C liquid helium) up to +260°C continuous, with intermittent resistance to +300°C.
Ultra-Low Coefficient of Friction
Static and dynamic friction coefficients are practically equal (0.05 - 0.10). Eliminates stick-slip and operates completely dry without grease.
Supplying Critical Industries Nationwide
Sag Engineers supplies high-precision sealing and fluid handling components to prominent manufacturing houses.
